Stirling engine does not burn liquid fuel, but outputs power through a cycle of cooling, compression, heat absorption and expansion of helium stored in the tank. It does not need ignition, does not knock, and the noise is quite low. It is almost the same as sailing with a battery.
At the same time, it does not directly drive the propeller at the tail, but drives a generator to power the whole boat and the motor at the tail to drive the submarine forward.
At this time, the Stirling engine is turning slowly, and the helium in the air storage tank is constantly working until the helium is exhausted, so you can't sail like this. Generally speaking, at that time, you have finished the combat cruise and returned to your home port.
"Accelerate to ten knots." Shepke gave orders.
When the Stirling engine is fully used, it can only reach a speed of five knots at most, and now in order to speed up the navigation, they have begun to use the power of precious batteries.
This submarine is improved by adding cabin sections on ordinary submarines. It retains the same battery as ordinary submarines. When necessary, the power of battery can also be used for silent navigation.
The speed of the five blade propeller at the tail is accelerated, but compared with the previous three blade propeller, the speed is greatly reduced, which makes it cause less noise and is not easy to be found.
They were originally wandering near Sevastopol, only 50 nautical miles away from the port, but now they can reach the port in five hours at a speed of 10 knots. If they catch up with each other and stop in the port, ambush is the easiest.
Below the command tower, the sonar is listening carefully to the sound in the sea.
In recent years, Germany's electronic technology has made rapid progress. Thanks to the miniaturization brought by transistors, sonar machines have made great progress. Now, the sonar ball in the front of the bow is receiving clutter around.
Listening in the clutter and discovering each other's surface ships and submarines is the task of sonar soldiers.
Time is passing by.
Shepke looked at his chart. The chief officer had marked the track on it. According to his voyage, he would reach Sevastopol in two hours.
At this time, suddenly, the sonar frowned. Among the numerous noises, there was a sound completely different, high-frequency, regular and rhythmic. It was the noise of the propeller!
"I found propeller noise, about 20 nautical miles away." Said the sonar.
Twenty nautical miles away, that means the other party has begun to leave the port! Shepke felt his adrenaline secreted rapidly. He felt so fresh because of the unique wet smell of diesel in the submarine.
"Rise to periscope depth." Cried shepke.
Just now, they have been sailing at a depth of about 50 meters. Now, the huge submarine begins to raise its head slowly. At the same time, a periscope rises slowly on the command tower.
If it is other submarines, they must raise the vent pipe at this time and use a short time to charge the battery. Now, they just need to raise the periscope.
At a depth of ten meters, the submarine leveled, shepke pushed the periscope in front of him and put his eyes on it.
Sonar in this era is not advanced enough to provide firing data for torpedoes. The attack on enemy warships still depends on periscope. At the same time, periscope is also needed to confirm the target.
When shepke fixed his eyes on the periscope, the sea was sparkling, and the quiet moonlight sprinkled on the whole sea. The surroundings looked very clear.
Well, the visual distance to see the outline of the enemy warship is at least three nautical miles, which is enough to identify the target.
Pushing the periscope, shepke's feet slowly turned. At the same time, the field of vision in the periscope was also turning. Suddenly, he was happy: "right rudder one, full speed!"
On the sea, you can see the flashing light, which is the navigation light turned on when the ship is sailing!
I didn't expect that the Soviets would turn on the navigation lights when fighting and sailing at this time.
After receiving the command of full speed forward, the sailor turned the operating lever in front of him to the position of forward five. With his toggle, the lights of the whole boat suddenly dimmed.
They still didn't turn on the diesel engine. They sailed entirely on their own battery power and the power of Stirling engine. The propeller at the tail accelerated and rotated to promote the water flow.
In the periscope, the target is getting closer and closer.
The other side is sailing at high speed. In this case, they can't find the underwater submarine at all. However, in case, they still don't start the diesel engine with the highest noise. At the highest speed, their power will be consumed quickly. When they get there, half of the power may be left.
If it is an ordinary submarine, no captain dares to do so. After all, the most precious thing for a submarine is electricity. If the electricity consumption is more than half, you have to think about charging at any time.
But now AIP submarines don't have to. They can use their Stirling engine underwater at any time without risking to rise to the vent pipe. If they really encounter a large number of enemy anti submarine operations, they will sit quietly and sink to the bottom of the sea and wait for the other party to go. If they can stick to it for a week, they will have more perseverance than anyone else.
Now, the U-100 has no scruples. They are sailing at high speed at a depth of 10 meters underwater, and the distance between them and each other is getting closer and closer.
"Left rudder one, stop and get ready to enter the ambush position." Shepke continued to give orders.
If submarines want to attack surface ships, they must pay attention to strategies. For example, the torpedoes used by submarines are mainly direct torpedoes. In this case, they must hit the largest projection area before they can hit, that is, the side of the other party.
Therefore, if the submarine wants to attack, it must occupy the attack position in advance and ambush on the other party's expected channel.
Now, the propeller at the tail of the submarine stopped rotating, and immediately the whole hull began to slow down. The rudder acted. The submarine slowly turned its nearly 2000 ton body and occupied the preset attack position.
Shepke's eyes kept staring at the periscope. The outline of the warship gradually emerged. Shepke was immediately excited after he saw it in the moonlight.
What do you want? It's the only battleship in the Black Sea fleet!
That battleship looks so magnificent. At the same time, the most exciting thing is that it is a lonely one. There is no escort warship nearby.
"Continuous noise, ten nautical miles away, a large number of warships are out." Said the sonar.
Please report us if you find any errors so we can fix it asap!
